IMPROVEMENT IN WINDOW SCREENS.

Specification forming part of Letters Patent No. 161,419, dated March 30, 1875; application filed February 13, 1875.

To all whom it may concern:

Be it known that I, LORENZO D. LocK- W'OOID, of Oharlestown, in the county of Windham and State of New Hampshire, have invented a new and valuable Improvement in Mosquito-Screens; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, and to the letters and figures of refer ence marked thereon.

Figure 1 of the drawing is a representation of a plan view of my device. Fig. 2 is a sectional view of the same, and Figs. 3, 4, and 5 are detailviews.

This invention has relation to mosquitoscreens for the prevention of insects from penetrating through an open window into the interior of a room; and the nature of the invention consists in certain novel means whereby the said net is rigidly but detachably secured to the edge-bars, all as will be hereinafter more fully explained.

In the annexed drawings, A designates one and B the other of two preferably-wooden bars, one of which is provided on its inner rounded and thickened edge with a cylindrical recess, a, and the other on its similarlyrounded edge with a screw-threaded perforation, I). Recess a is in the nature of a socket, and is designed to receive a correspondinglyshaped end of a tension-rod, G, which has upon its other end a screw-threaded ferrule, adapted to be received in screw-threaded perforation b of the rod B, as shown in Fig. 1. Bar A is composed of two partsa rectangu- .1ar strip, 0 and a U-shaped piece, j, within which the former is adapted to be received, as shown in Fig. 3. Strip 6 is provided with a deep narrow groove, '5, into which the edge of the net D is forced. One or more turns is then given to the said strip, when it, along with the folds of the net, is forced into the U-shaped strip j, when the said bar will present the appearance in cross section shown in Fig. 3. The opposite edge of the net I) is forced into a similar groove, 1, in the outer surface of the bar B, as shown in Fig. 5.

What I claim as new, and desire to secure by Letters Patent, is-

l. The strip 6, having the groove 45, for the reception of the net I), in combination with the bar A, having the recess j, as described.

2. The bar A, having the recesses a the strip 6, provided with the groove '5, and the bar B, having the groove l, in combination with the tension-rod O, substantially as described.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

LORENZO D. LOOKWOOD.
